This is a remarkable piece of music written by Charles Ives, the Ives in
Currier and Ives Ives & Myrick (Thanks for the correction, Joe Barron!), by the way. We played this piece in band in high school and it was my first introduction to modern orchestral music. It took "America" and twisted it from different perspectives. I was in love.
What is remarkable to me is that it was the first time I'd heard someone rearrange something so familiar and traditional into an abstract and eerie landscape. It made me feel like this was the right version of the song. It has flavors from different cultures, there is dissonance, kind of like the real America. As a country, we are less like a sacred hymn and more like a sacred carnival.
Grab some cotton candy and enjoy.
For to be free is not merely to cast off one's chains, but to live in a way that respects and enhances the freedom of others.
